' MacII'INEron srINNING ARTIFICIAL SILK.v

To all whom it may concern:

Be it known that I, HILAIRE DE CHARBON- Nn'r, a citlzen of France, residui Place Malesherbes, Paris, -in the epublic of France, have invented new and useful improvements in Machines for Spinning Artificial Silk, of which the followingis a specification.

This invention relates to improvements in machines for spinning artificial sllk from collodion, of a uniform 'composition throughout.

The invention consists of a novel combl-l nation and arrangement of parts characterized bythe fact that the group of 'threads to be wound,together` on each bobbin and subsequently twisted' are assembled on a separate feed table which is supplied with collodion by means of a two-barrel feed pump, the movements of the pump plungers Specivtion @LI-etterllt'eltt vPatented Dec. l19, 1916.

`F1gure 11 1s a transverse vertical section of the wholey machine, the section beingA coacting so as to insure a constant uniform flow of collodion to the feed table. movement of each )ump plunger when forcing the collodion through the spinning nozzles is slower than the indrawing movement of the same whcnlilling the pump barrel so that one plunger continues to feed the collodiop while the distribution-cock of the other barrel is turning at the end of every stroke, whereby all interruption to thehoutiow of collodion at the dead point is avoided while slight variations in the collodion iiow are compensated automatically by a spring pressure regulator or accumulator onA each feed table. l

The pump barrels are divided into two sets or series, the plungers of each series being actuated alternately dion into the feed tables.

The collodion entering the pump barrels' under pressure tends constantly to raise the n pum plungers, this tendency beinglcounteracte to the extent ofthe minimum pressure used in spinning by counter-,weights applied' under the plunger-s so that the power-necesto force the collo- The sary to force each plunger and its connec tions downward against the Aresistance of the collodion corresponds to the difference between the maximum and minimum pressures reached in spinning. l

A constant count (t-iterage) of thread is obtained by maintalning an invariable ratio between the bobbin surface speed and ,the flow of collodion supplied to each group of capillary glassA spinning nozzles, -the threadsfrom which are wound together made on the plane of the line A A, Fig. 3.

The improved machine forming `the subject ofthe invention is in the same gemaralA h form as other known machines for spinning 100 articial'silk from collodion or the like'` an -1sr mclosedV 1n a casing as sometimes cusgauzenvw ichare set aside to get lat the threads. These curtains or glasses, not

shown, are suspended uponv the framing at.

a.. The machineis' closed aboveby panes of glass b,l which are opened when required forI tomary. `lThe vcasing is in this instance closed'. 'in front ofthe threads, either by movablepanes of lass or by curtains of'transparent ros hand side-of Fig. 1., upon which are placed the full bobbius c', shown on the opposite side of the saine figure, to allow thein to dry partially.

To accelerate the descent ol the air, charged with heavy vapors, toward the bottoni of the machine, whence it is drawn E by afan or equivalent toward the rcgenerating apparatus, an uncongealable cooling liquid can be caused to circulate nl tubes'e, either plain or ribbed.

The capillary spinning nozzles 2 (sec .1"ig. feeding ay given bobbin are asof a. tubular column i, slotted at the sides tov .receivethe ends of a guide bar or crosspiece senibled upon a circular feed table f inount-l ed upon a hollow vertical spindle f2, shown in Fig. 12, rotating in a water-tight packing, and through which the collodion is in-v jected 'into the feed table f through a' filter 'f'. rl`his feed table f carries as many spinning nozzles 2 as the-threads that are to be assembled upon a. given bobbin. In Fig. l1 it has been assumed that there were ten nozzles to one bobbin'; but only two are shown in position on Figs. 10 and 11. ln this way', each nozzle 2 can be brought forward when .required The fixed lower part of the leed table j' containing the water-tight packing is bolted toa girder-beaiu ol the training and carries a three-way cock Il enabling the eollodion to be run oll' it necessary.

In the middle ot the feed table f islarranged vertically a pressure regulator consisting ofa coiled spring /t or its-equivalent. This pressure regulator. as shown is forn'ied connecting the packed plunger :rod or pistou fc to a tube which islittod to slide vertically upon the column the tube j is iunged at the bottom to l'orni a shoulder which acts as an abutment for the spring It.

At the top of column i is screwed a ring or collar m which acts as the upper abutment for the spring h, and uponwvhich' is placed a, ring u. which carries the thread-guides o. rl`he ring u must be removed temporarily to allow a cap or casing l to be placed over the spinning nozzles. i

The ilow' of collodion ibein'g constant, if the outlet through the spinning nozzles 2 offers more. oi: less resistance on. account of accumulation of dirt or Jtroni any other cause, the spring lf. furnishes automatically the requisite,pressure l'or the outlet ol' the eollodion whlch is thus ell'ected in a constant volume and undeia v-\'ariablepressure Vhon.- the spinning `is interrupted, the spinning nozzles 2 inust berovered with the annular cap or casing L; which prevents ,hardeningpof the colloc-lion andffacilitates restarting the machine.

Each vspinninghead or feed table f reoeyes .the eollodion from a pump formed of two separate barrels 7 and p. One of tliese barrels isseen on a larger .scale Figs. 14

and l5. The inoton olI the plunger f/ ol' each barrel is regulated so as to run inorn slowly when l'orring the rollodion into the spinning nozzles 2 is taking place. 'l`he object ol' this arrangement is to prolong the action ol' the plunger q ol one ol' the puinp-lmrrels duringr the action ol the valves or taps ol' the other |uunp-barrel, and taking into account the lostniotion', lt results l'roni this that the low of the eollodion is constant as no dead point can exist. lt is only to guard against any possible irregularities ol working that theI above Adescribed auxiliary spring regu-`r ylator /i has been adopted.

The dill'erentiul plunger r/ ol each ol' these single-action"` pumps p /1 traverses it from one end to the other in glands or stulling boxes. The

than when the surtiony collodion is l'orred into the spinning nozzlesy 2 when the plunger l/ dest-ends, according to the (bill-renee ol'. diameters at the top and at the bottoni. "l`he rollodion arrives lroni .the supply pipe ,r/ under pressure, sotliat thc plungers l are always raised by the collodion, but this pressure is iannpensattul'in the l'ollowuig manner.: All the pump-barss l rels ofthe machine are divided into two Sets.y

bar ll.

Under each of the racks 71' '1" is a beaux t ylnoi'able vertically along'slides u. These beams run the length `ol'the machine; each ol' theni is lorined of a lat plate placed \er-- tirally, andl provided with horizontal llanges; the upper yflange is provided with holes through which pass the rods l] of the` punip plungers. A was ier q 4and a nut q2, f

see Figs. 14. and 15, screwed lo the bottoni of the rod, draw down the plunger r/ when the beam f descends. Under the beams t are suspended counterweights Au which arer regulated so as tobalancetlieinininuun pres` sure of the eollodion `under the plunger-sk q. lt' left to 7the sole action ofthe c0llodion,the system formed by theplungers (j, the beams stantly brought back to the top of its stroke.

.'lhe. power y,net-.essa ry to move this system, will betheretore always directed froi'u above to below, but vit will never exceed the difference o he inaxnnlun and minimum pressui-es used in spinning and acting Iunder the plungers q; this effect will thus be reduced to a in iniinuntf' V p, I y To cause thebearns t tcyttravel with unifornii n ioveinents l upward jmd downward `at therespective rspeeds r 4 aired, each beam .is provided, `near both len4 s,with rollers Qa:

whichl move in thealgrooved, paths 'z z (see Figs. Qtand 7 inkthesdes` oa cum pullev l and the rounterweights o, would he con-t ycam pulley y at each end and both y whose grooved paths have different inclines proportioned to the vertical speed of translation in each direction. There is a iilleys y are rotated at a constant speed'as liereinafter described.

i At each end of the stroke one of the plunygers g continues to thrust the collodion "whi'le the other is at.dead point and while the distribution-cock N of this latter takesup the new position. On Fig. 7, the path z which corresponds tothe plungers of the pumps 71, is shown in full lines, while the path e corresponding to the plungers of the pumps p and which is situated on the opposite side of the cam'pulley y is indicated in dotted lines.

To effect the rotation of all thedistribution-cocks N of a given set, the rim of each cam pulley y is provided, as shown in Fig.

8, with say three'or it might be two circlilar grooves 4 connected with each other by oblique grooves 5,' which correspond each one to the angle of positionoccu'pied by the 'cam pulley y at the moment in which the cocks have to move.

Studs or rollers I. (see Fig. 2) running in these circular grooves 4 and passing from one to the other by the oblique grooves 5 at the 'right moment, transmit ,their 'lateral movement by a set of connecting rods which are clearly seen in the plan Fig. 3, and by?- means of a vertical shaft carrying two disks E the lower disk E having two bars F piv otally connected-to it and running along the machine above the distributionwei N.

The fixed center T of the connecting rod system is mounted upon a bearer or cradle connecting-the two racks r r above the cam pulley y. The bars F (see Fig. 17) carry studs corresponding to holesin the doubleended spanners G of the distribution-cocks N and thus cause themall to tate simultaneously.

The shaft H of each cam pulley carries a 'worm Wheel'K gearing with .a 3dorm L, keyed upon a driving, shaft M e ending from one end to the other of the acl'iine partially ro and thus causing bothcam pulleys to be rotated at the same speed. The shifft M is connected by gearing or belt to the axle or' the drum by which the bobbins are driven by frictional contact to insure that the two speeds of drawing and of flow of collodion) shall be in a constant ratio corresponding to the required count of the thread or yarn.

Each distribution-cock N has three outlets and makes quarter of a revolutionl at each; end of thestroke, so that these cocks place successively their respective pump-barrels in.
